High-strength polyethylene pipe for building

Abstract

The invention belongs to the technical field of polyethylene pipes, and specifically discloses a high-strength polyethylene pipe for a building. The high-strength polyethylene pipe for the building comprises an outer pipe body, an inner pipe body, a support module and a buffer module, wherein the outer pipe body sleeves the outer side of the inner pipe body, and an annular cavity is formed betweenthe inner wall of the outer pipe body and the outer wall of the inner pipe body; the support module and the buffer module are arranged at the inner side of the annular cavity; and the support modulecomprises a first annular steel sheet, a second annular steel sheet and insertion-connection teeth; the first annular steel sheet is arranged on the inner wall of the middle part of the outer pipe body; the second annular steel sheet is arranged on the outer wall of the middle part of the inner pipe body; and the insertion-connection teeth are arranged on the adjacent sides of the first annular steel sheet and the second annular steel sheet separately. According to the high-strength polyethylene pipe for the building, the outer pipe body and the inner pipe body are supported through the co-action of the buffer module and the support module, so that the buffer efficiency is effectively increased; and force relief is carried out between the outer pipe body and the inner pipe body by virtue of a cross elastic frame or an elastic packing auger, so that the damage probability of the outer pipe body due to local stress is lowered, and the service life of the polyethylene pipe is prolonged.

Description

technical field [0001] The invention belongs to the technical field of polyethylene pipes, in particular to a high-strength polyethylene pipe for construction. Background technique [0002] Polyethylene is a highly crystalline, non-polar thermoplastic resin. The appearance of the original polyethylene is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial chemicals. With the progress of society, due to the convenient installation and reliable connection of polyethylene pipes, it can be used for the layout of cables or the transportation of fluids, the raw materials can be recycled, the equipment requirements are simple, the production process is simple and easy to control, and a series of advantages such as random pipeline layout. , The application of polyethylene pipes is becoming more and more extensive. After the polyethylene pipe is buried in the ground, it will cause unnecessary bending of ...

AI Technical Summary

Problems solved by technology

[0004] Although this technical solution can increase the rigidity of the polyethylene pipe by overlapping the nested tapered pipes, it can avoid the stretching of the pipe wall caused by the unnecessary bending of the pipe by external force after the polyethylene pipe is buried. , thereby reducing the wear resistance of the outer tube wall. However, when the polyethylene tube is bent, the inclination of one end of the tapered tube increases, and it is easy to produce local extrusion on the inner wall of the outer tube, resulting in the outer tube from Therefore, a high-strength polyethylene pipe for construction is proposed.
